/usr. Port Fedora 17 iputils-20071127-infiniband.patch, which inlines
access previously done by libsysfs.

+arping: Break libsysfs dependency

+Port Fedora 17's iputils-20071127-infiniband.patch, which inlines sysfs
+access previously done by libsysfs (which is in /usr, and thus not
+usable by /bin/arping).
